Seoul Semiconductor, a global leader and innovator of LED products and
technology, exhibited its new SunLike Series LEDs, the world's first LED
to produce light that closely matches the spectrum of natural sunlight,
at the recent Professional Lighting Design Conference (PLDC), held in
Paris, France from Nov. 1 – 4. The new LED technology, first unveiled in
Frankfurt, Germany in June of this year, is generating interest from
many global lighting companies, who are developing new lighting products
using SunLike Series LEDs.

New products from leading lighting designers powered by Seoul
Semiconductor’s SunLike LED technology were on display at PLDC 2017,
which attracted more than 2000 attendees. A number of these companies
signaled their intention to launch these new SunLike-powered lighting
products in the market.

The director of Seoul Semiconductor's Lighting Divison, Mr. Yo Cho, was
invited as a keynote speaker at the PLDC’s opening event, where he
presented SunLike Series LED technology. “Because the SunLike Series
LEDs are designed to deliver light that closely matches sunlight’s
natural spectrum, they provide an optimized light source that maximizes
the benefits of natural light,” said Mr. Cho. “Thus, the colors and
texture of objects can be viewed more accurately, as they would be seen
under natural sunlight.”

According to Dr. Kibum Nam, Head of Seoul’s R&D Center and Chief
Technology Officer , “SunLike Series LEDs have the potential to drive a
revolution in lighting –overcoming the limits of artificial light
sources by implementing light closer to the natural spectrum of
sunlight. Seoul will open a new era of natural spectrum lighting with
the launch of more SunLike LED technology.”

SunLike Series natural spectrum LEDs may also play a key role in
minimizing the negative effects of artificial lighting. While
conventional LED technology produces light with a pronounced blue
“spike” in its spectral output, SunLike LEDs implement a more uniform
spectrum that more closely matches natural sunlight, lowering this blue
light spike. Some recent research indicates that this blue light spike
may produce negative effects when viewed for prolonged periods of time
during night-time hours, potentially interfering with natural human
biorhythms. By employing new light sources powered by SunLike Series
LEDs, lighting designers will be able to deliver a healthier light
experience.

Interest in the link between light sources and human health is higher
than ever before, as evidenced by the winners of this year’s Nobel Prize
in Physiology, Professor Jeffrey C. Hall, University of Maine; Professor
Michael Morris Rosbach, Brandeis University; and Professor Michael
Young, Rockefeller University. These researchers are credited with
seminal discoveries about the cellular mechanisms for circadian biology.
